You’re going to call down the wrath of the frightened bunnies who believe there’s a deranged gunman hiding in the bushes of every school in America.
Statistically the number of school shootings (aside from inner city gang violence) is so low that we can never really effectively bring the number down.
Personally I think the best thing you can do is eliminate the gun free zones and allow staff to carry. These shooters don’t appear to be risk takers. They plot and intend to die. Make them gamble and you may just deter some of them.
I agree. Take down all gun free zone signs and let the staff do as they wish.
